The webs between the distributthat part oi the assembly thereof with which ing channels 10 of the head 8 are provided the valve is associated. comprises, for the with an opening 28 between each pair of most part, a cylindrical pipe housing 5, the the distributing channels for suspendin the upper end of which is seated in an anrrflnr light sockets 29, with the light bu1bs'30t erethe central bore 9 of the head 8. One of the light cords may. lead toa light socket 31 which is threaded into the top part 32 of the dome 26,

Referring now to the detail construction I of the valves which are mounted to the ends of the oil cylinders 15, attention is directed particularly to Figs. 2 to 5, inclusive.

Since all of the valves are identical in their construction and combination of parts, only one of thesame will be specifically referred to.

The housing 17 is preferably produced as a casting having a lower threaded end 33 for the reception of the cap closure 34, the same havinga central bore 35 which serves as an outlet for the oil. The construction of the cap 34 includes an annular countersink or recess 36 for holding a packing 37 which serves as a soft, resilient seat for the circular rib 38 on the bottom of the valve 39" and as a gasket for the cap closure 34. The valve is further provided on its bottom with a central plug or plunger 40 which is positioned co-axially with respect'to the outlet bore 35 which it occupies when the valve is closed. The plug will serve to dispose of the oil in the bore 35 as the rib 38 comes to rest on its seat 37. The valve 39, as is best illustrated in the horizontal sections 3 and 5, is made with diametrically opposed radial projections or ribs 41. These ribs extend from the top of the valve flush with the bottom thereof, terminating above the rib 38. The

sides of the ribs 41 have a ground fit with the cylindrical interior wall of the housing 17 but the fit is sufliciently free to permit the valve to be moved up and ,down'within the housing. One of these ribs, namely 42, is

much thicker than the other three and is arranged opposite the space 43 which communicates with the interior of the valve housing and is formed in a projection 44 on one side of the housing. The space 43 serves to accommodate a pinion 45 which is positioned to mesh with the rack teeth 46 on the face of the projecting rib 42. The pinion 45 is fixed upon a shaft, 47. One end of this shaft in advance of the pinion 45 is journaled as at 48 in a bearing provided in the projecting side 44 of the valve housing.

The shaft is provided with a ring 49 which is made to fit the circular reduced diameter of the opening between the shaft housing 50 and the space 43. This ring serves as one barrier to prevent leakage of oil through the shaft housing and also as a centering bearing for the shaft. The stufiing box in the shaft housing is provided by internally threading the endof the shaft housing for the shaft and against the beveled end of' the housing just in front of the ring 49. A lock nut 52 maybe threaded on the gland 51 to hold an adjustment thereof.

' I The rotation of the shaft 47 is effected by the winged handle 53, the collar 54 thereof being slipped over the end of the shaft housing 50 as a cap and having a central opening through which the threaded end 55 of the shaft extends. A washer 56 and nut 57 holds the cap on the shaft.

The valve 39 is made with an opening 58 co-axially disposed relatively ofthe plunger 40 for the coiled spring 59. The uppercoils of this spring are wound around the end of the rod 18 and bear against the under side of the sleeve 23 so as to impart a downward thrust to the valve and hold it seated under tension.

When it is desired to draw a quantity of 2 oil, a suitable measure is placed below the valve which controls the outlet of oil from the cylinder containing the grade of oil desired and the handle 53 is then turned to the left, as an example. This rotates theshaft 47 and the pinion 45. The pinion being in constant mesh with the rack face 46 on the rib 42 will elevate the valve 39 against the resistance of the spring 59, raising the rib 38 oil its seat and withdrawing the ,plug.

or plunger 40 out of the bore 35. The oil is supplied to the cylinders 15 under pressure and they .are maintained full at all times.

Since there is no obstruction between the cylinders and the lower part of the valves, the oil feeds down the open spaces around the valves, between the ribs 41 and the rib 42 into the flared area over the. packing 37 where it is obstructed by as a seal. l/Vhenthe valve is raised, the rib 38 is raised off its seat upon the packing and.

the plunger 40 is raised out of the outlet bore, as stated, which leaves an unobstructed outlet for the oil through the boreinto the measure.

.The cut-ofl' is effected by turning the handle in the opposite direction which closes the valve with the aid of the spring 59.

As indicated by the dotted lines in Fig. 4, the outer walls of the valve 39 between the

radial ribs

41 and 42 are slightly slanted from top to bottom whereas the faces of the ribs are perpendicular.

The cap closures 34 for the valves are knurled, as best shown in Fig. 1. This pro vides a roughened hand grip by which the caps may be screwed on the valve housings so as to jam the packing 37 tightly up against the edge of the housings to make a leak-proof connection.
